John 10:17  Therefore doth my Father love me, because I lay down my life, that I might take it again.

18  No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.


Too  many Christians forget that the base of Christianity is Yeshua's resurrection and not his death, although he would have to die to before he could be resurrected.  The Romans were accessories only in that they were law over Jerusalem. And the accusations to Pilate were that Yeshua called himself a king (although he told Pilate that his Kingdom was not of this world). However this would be treason to Caesar in the providence. 


The crucifixion was a form of death, there were so many others, but this one was public which was the required way for the sacrifice to take place.  Remember Passover, this happened at Passover as it should because the Passover not only symbolized the deliverance of the Tribes of Israel from bondage of Egypt but was also a forecast symbol of Yeshua's great sacrifice to release us form the bondage of sin. 


We know in Matthew 26:39  And he went a little farther, and fell on his face, and prayed, saying, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt.


Yeshua realized that there was no other way. 


In Isaiah 53:2, God shows that it was his plan, although He knew his Son would be wounded and afflicted and CUT OFF (killed). 

2  For he shall grow up before him as a tender plant, and as a root out of a dry ground: he hath no form nor comeliness; and when we shall see him, there is no beauty that we should desire him.

3  He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we hid as it were our faces from him; he was despised, and we esteemed him not.

4  Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted.

5  But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.

6  All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all.

7  He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.

8  He was taken from prison and from judgment: and who shall declare his generation? for he was cut off out of the land of the living: for the transgression of my people was he stricken.

9  And he made his grave with the wicked, and with the rich in his death; because he had done no violence, neither was any deceit in his mouth.

10  Yet it pleased the LORD to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand.


During the uproar of The Passion of Jesus Christ, when it was argued so much over who killed him, the Jews or the Romans, or who was the "bad guy" to me was so unnecessary as it was God himself who ordained Jesus (Yeshua's) death. 


As for the Jews involvement, although it was crooked priests that tried to trap him all of the time, and God allowed Satan to pull his normal activities with mankind, the sacrifice had to be made and and the Passover Lamb had offered up by the priestly tribe, the Jews.
